Fire Retardant Resin Manufacturer
Safety Without Compromise
Advanced UL94 V-0 and ASTM E84 Class 1 certified formulations for critical safety applications.
When Safety is Paramount
In modern construction and mass transit, fire safety regulations are stricter than ever. Fire retardant resins are essential for manufacturing composites that resist ignition and limit the spread of flames.
Changyuan New Materials engineers FR resins that not only meet rigorous flammability standards but also maintain the ease of processing and durability you expect from high-quality composites.
From halogen-free systems for subway interiors to chemical-resistant FR vinyl esters for industrial scrubbers, we provide the certified protection your projects require.

Fire Retardancy FAQ
Q: What standards do your fire retardant resins meet?
Our FR resins are formulated to meet major international standards including ASTM E84 (Class 1 & 2), UL 94 (V-0), and European railway standards EN 45545-2 depending on the specific grade selected.
Q: Is fire retardant resin transparent?
Standard FR resins are typically opaque or translucent milky white due to the additives (like ATH or halides). However, we offer specific 'Translucent FR' grades for manufacturing rooflights that require light transmission.
Q: Does fire retardant resin lose mechanical strength?
Heavily filled FR resins (like ATH filled) can have slightly different mechanical properties compared to unfilled resins. We optimize our formulas to balance fire safety with the necessary structural integrity for your application.
Q: Can I use standard catalyst with FR resin?
Yes, standard MEKP catalysts are generally used. However, cure characteristics might differ slightly due to the retardants, so we recommend conducting a small cup gel test before large-scale production.
